Featuring our proprietary active noise cancelling system, the AH-GC20 can reduce or eliminate ambient noise effectively, and can be used when playing music, making phone calls, or by itself to give you peace and quiet in a noisy environment. Dual microphones on each earcup (one inside, one outside) help deliver remarkable voice clarity when making and receiving phone calls and contribute to the exceptional noise cancellation performance.

With the AH-GC20, there's no need for a cable to enjoy your favorite music on your portable device, and the AH-GC20 features dual simultaneous device connectivity. For example, you can listen wirelessly to your iPad or iPod touch and send and take calls from your iPhone, and the AH-GC20 features Apple's Siri voice command system compatibility, including voice prompts to advise operating status and battery life, with your choice of 7 different languages.

Along with aptX Low Latency wireless audio coding that provides CD quality audio, the AH-GC20 is also equipped with Clear Voice Capture, a sophisticated noise reduction system which enhances received audio quality and includes noise suppression, adaptive equalization, automatic gain control, echo cancellation, wind noise reduction and noise dependent volume control, all designed to deliver the clearest voice quality even in harsh noisy environments.

Equipped with large 40mm professionally tuned drivers, the AH-GC20 benefits from Denon's many years of studio and professional headphone expertise, delivering a natural tonal balance free from exaggerated colorations. While so many headphone brands have appeared lately, Denon has decades of advanced headphone development know-how. In fact, we've measured more than 4,000 people's ears and distribution of facial structures, to ensure that everyone everywhere can enjoy the best in sound quality and comfort.

Equipped with memory foam earpads, the AH-GC20 features comfortable over-ear fit along with fatigue-free listening due to the use of advanced lightweight materials, including aluminum alloy spur hangars that feature dual axis rotation, along with a lightweight padded headband. Weighing in at only 9 ounces, the AH-GC20 lets you listen in comfort, even over many hours.

Designed for Denon Globe Cruiser headphones, our Denon Travel smartphone app is the perfect complement to the AH-GC20, giving you fingertip control with a range of functions, and it's available in iOS and Android™ versions for compatibility with the widest range of smartphone models.

While AH-GC20 owners will undoubtedly be listening wirelessly via Bluetooth most of the time, we also include a headphone cable when wireless usage isn't permitted (such as airplane take-offs and landings). The kit also includes a 3.5mm-¼" standard headphone plug adaptor for connection to home and studio audio gear, as well as an airplane adapter plug. The included USB Micro-B cable lets you charge the AH-GC20 lithium-ion battery from any USB charger or computer USB port. To enjoy up to a full 20 hours of wireless listening, the AH-GC20 recharges in only 3 hours. If the battery is depleted and there's no USB port for recharging available, you can still enjoy listening to music via the included audio cable.

We also include a deluxe carrying case for the AH-GC20 headphones and the accessories, to keep everything together when you're on the go.
